Intel E3-1220 v3 overview

1Description

The Xeon E3-1220 v3 3.1 GHz Processor from Intel is equipped with 4 cores and 4 threads and can be installed in the LGA1150 socket. It delivers an improved automatic performance, thanks to its Intel Turbo Boost 2.0 technology. This gives system builders the freedom to set their computers the way they want by overclocking the processor's original speed of 3.1 GHz to up to 3.5 GHz. The Xeon E3-1220 Processor also features advanced technologies such as Intel Virtualization technology, Intel Trusted Execution technology, Intel 64, Enhanced Intel SpeedStep technology and more.

Intel Turbo Boost 2.0 Technology

Intel Turbo Boost technology dynamically increases the processor's frequency as needed, by taking advantage of thermal and power headrooms. This allows the processor to run faster and makes it more energy efficient.

Intel Virtualization technology for Directed I/O (VT-d) continues from the existing support for IA-32 (VT-x) and Itanium processor (VT-i) virtualization, adding support for I/O-device virtualization. Intel VT-d can help improve security and reliability of systems as well as performance of I/O devices in virtualized environments.

Intel VT-x with Extended Page Tables (EPT)

Intel VT-x with Extended Page Tables (EPT), also known as Second Level Address Translation (SLAT), provides acceleration for memory intensive virtualized applications. Extended Page Tables in Intel Virtualization technology platforms reduce memory as well as power overhead costs and increase battery life through hardware optimization of page table management.

Intel Trusted Execution Technology

Intel Trusted Execution technology for safer computing is a versatile set of hardware extensions to Intel processors and chipsets that enhance the digital office platform with security capabilities such as measured launch and protected execution. It enables an environment where applications can run within their own space, protected from all other software on the system.

AES New Instructions

Advanced Encryption Standard New Instructions (AES-NI) are a set of instructions that enable fast and secure data encryption and decryption. AES-NI is valuable for a wide range of cryptographic applications, including applications that perform bulk encryption/decryption, authentication, random number generation and authenticated encryption.

Intel TSX-NI

Intel Transactional Synchronization Extensions New Instructions (Intel TSX-NI) are a set of instructions focused on multi-threaded performance scaling. This technology helps make parallel operations more efficient via improved control of locks in software.

Intel 64 Architecture

Intel 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms when combined with supporting software. It also improves performance by allowing systems to address more than 4GB of both virtual and physical memory.

Idle States

Idle States (C-states) are used to save power when the processor is idle. C0 is the operational state, meaning that the CPU is performing useful task. C1 is the first idle state, C2 the second and so on, where more power saving actions are performed by numerically higher C-states.

Enhanced Intel SpeedStep Technology

Enhanced Intel SpeedStep technology is an advanced means of enabling high performance while meeting the power conservation needs of mobile systems. Conventional Intel SpeedStep technology switches both voltage and frequency in tandem between high and low levels in response to processor load. Enhanced Intel SpeedStep technology builds upon that architecture using design strategies such as separation between voltage and frequency changes and clock partitioning and recovery.

Thermal Monitoring Technologies

Thermal Monitoring technologies protect the processor package and the system from thermal failure through several thermal management features. An on-die Digital Thermal Sensor (DTS) detects the core's temperature. Thermal management features reduce package power consumption and thereby temperature when required in order to remain within normal operating limits.

Execute Disable Bit

Execute Disable Bit is a hardware-based security feature to help reduce exposure to viruses and malicious code attacks. It also helps prevent harmful software from executing and propagating on the server or network.

Intel Identity Protection technology is a built-in security token technology that helps provide a simple, tamper-resistant method for protecting access to your online customer and business data from threats and fraud. Intel IPT furnishes a hardware-based proof of a unique user's PC to websites, financial institutions and network services, providing verification that it is not malware attempting to login. Intel IPT can be a key component in two-factor authentication solutions to protect your information at websites and business log-ins.

Note:*This feature may not be available on all computing systems. Please check with the system vendor to determine if your system delivers this feature or reference the system specs (motherboard, processor, chipset, power supply, HDD, graphics controller, memory, BIOS, drivers, virtual machine monitor-VMM, platform software and/or operating system) for feature compatibility. Functionality, performance and other benefits of this feature may vary depending on system configuration.
